Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A toe made up of two or three boens called phalanges.






2. The shaft portion of a long bone.






3. Small bones shaped like cubes or marshmallows; an example are the carpal bones.






4. The joint between the femur and the tibia; called the knee joint in humans.






5. The main - weight - bearing bone of the lower leg; forms the stifle joint with the femur proximal to it and the hock with the tarsus distal to it.






6. The area of a bone that joins the head with the main portion of the bone.






7. A spheroidal articular surface on the proximal end of a long bone; present on the proximal ends of the humerus - femur - and rib. Joined to the shaft of the bone by an area that is often narrowed and called the neck.






8. The solid structure formed by the fusion of the sacral vertebrae.






9. A skull bone that is one of the external bones of the cranium; the caudal - most bone of the skull that forms the atlanto - occipital joint with the first cervical vertebra through the occipital condyles. The large foramen magnum in the occipital bon






10. Also called a spheroidal joint - it consists of a spherical joint surface (the ball) that fits into a closely matching - concave joint surface (the socket). Examples: shoulder and hip joints. Capable of all synovial joint movements.






11. The fluid - filled potential space between the joint surfaces of a synovial joint; normally filled by synovial fluid.






12. A skull bone; one of the external bones of the face. It is the lower jaw - the only movable skull bone - and contains all of the lower teeth.






13. A slightly movable cartilaginous joint - such as the pubic symphysis.






14. Incoordination; animals with this make jerky - spastic movements.






15. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






16. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






17. A beak - shaped process at the proximal end of the trochlear notch of the ulna; when it fails to unite with the ulna - an ununited process can cause the elbow joint to become unstable - leading to lameness.






18. A flat articular surface - such as between carpal bones and between the radius and ulna.






19. A bone of the sternum.






20. A depressed or sunken area on the surface of a bone; usually occupied by muscles or tendons.






21. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






22. A gliding joint in which two flat - articular surfaces rock on each other; this type of joint usually allows only the movements of flexion and extension.






23. The joint composed of the carpal bones; referred to as the 'knee' of the horse and the 'wrist' of humans.






24. A skull bone; an internal bone of the cranium. This single bone is located just rostral to the sphenoid bone and contains the cribriform plate.






25. The cartilaginous ventral portion of a rib.






26. Viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates joint surfaces.






27. One of two bones (the radius is the other) that form the antebrachium - or forearm; forms a major portion of the elbow joint with the distal end of the humerus.






28. The skull bones that do not surround the brain. External bones: the incisive bones - the nasal bones - the lacrimal bones - the maxillary bones - the zygomatic bones - and the mandible. Internal bones: the palatine bones - the pterygoid bones - the v






29. The smooth joint surface of a bone that contacts another bone in a synovial joint.






30. The cells that produce bone.






31. Skull bones that are part of the internal bones of the face; also known as the nasal conchae. Four thin - scroll - like bones that fill most of the space in the nasal cavity.






32. The group of vertebrae located dorsal to the abdominal region.






33. Another name for cancellous bone.






34. Another name for a pivot joint; one bone pivots on another in a rotary motion. The only true pivot joint is the atlantoaxial joint.






35. The bone in the neck region that supports the base of the tongue - the pharynx - and the larynx - and aids the process of swallowing. It is usually referred to as a single bone - but it is composed of several portions of bone and cartilage.






36. An alternate name for joint cavity.






37. The bones of the carpus; consist of two parallel rows of short bones located between the distal ends of the radius and ulna and the proximal ends of the metacarpal bones.






38. The paranasal sinus in the maxillary bones.






39. The outer layer of a bone that is composed of compact bone.






40. A freely movable synovial joint.






41. The epiphyseal plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. Areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full size - thes






42. The single - dorsally projecting process of a vertebra.






43. One of the two bones (with the ulna) that form the antebrachium - or forearm; usually the main weightbearing bone.






44. The junction between two bones; can be completely immovable (fibrous) - slightly movable (cartilaginous) or freely movable (synovial).






45. A joint whereby one surface swivels around another like a door hinge; also called a ginglymus joint. The only movements possible are flexion and extension; the elbow is an example.






46. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






47. The 'forearm' region of the thoracic limb.






48. Another term for the diaphysis of a long bone.






49. A ball - and - socket joint - such as the shoulder or hip joint. Capable of all synovial joint motions.






50. Bony arches below and behind the eyes of common domestic animals; in dogs and cats they form the widest part of the skull. Made up of the rostral - facing zygomatic process of the temporal bone joined with the caudal - facing temporal process of the
